Vitamin D defeceincy? D def or else?

Hi Sir, This is to inform you that I am feeling hot in the body since a year but recently hotness get more & more & now i feels like a fire in my body. This is not fever as well because i have consulted to many doctors & there is no sign of fever when they checked by fever checker. As suggested by one of the doctor i hav done my all reports to analyse the cause but all reports came normal except vitamin D defecency. It is 13.2 under 25 OH VITAMIN D TOTAL test system. Earlier i was taking acenova medicine for two months at that time it was stop hotness in my body but after the advise of doctor i need to stop this medicine as this is pain relief & having side effects as well if takes for a longer period of time. So my question is why very hot in my body occuring? Is this because of vitamin d def or else? Just for your info i have also taken vitamin d  8 tablets once in week for 2 months.
